JAMES MILLAR AND GEORGE FEENY, OF AMABEL, ONTARIO, CANADA.

BOILER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 348,530, dated August31, 1886,

Application filed Noremher11,1885. Serial No. 182,449. (No model.)

To all whom it may concern:

Be it known that we, Janus MILLAR and GEORGE FE'ENY, subjects of theQueen of Great Britain, residing at- Amabel, in the county of Bruce,Province of Ontario, Dominion of Canada, have invented a new andImproved Boiler-Cleaner, of which the following is a full, clear, andexact description.

Our invention relates more particularly to a permanent attachment to theboiler, although the device is applicable to certain forms of boilerwhich were not originally made with reference to the use of such aninstrument as we are about to describe.

The invention consists of a brush formed from steel wire mounted in ahead that is hinged to a block fixed on one end of a manipulating bar orred. This rod passes loosely through the block, and upon either sidecarries two arms or lugs, which project at right angles from the rod.

Reference is tobe had to the accompanying drawings, forming part of thisspecification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal vertical sectional view of a boiler providedwith our improved form of cleaner. Fig. 2 is a view of the rear of theboiler, a portion of the casing being removed to disclose theconstruction of the boiler proper. Fig. 3 is a plan view of the cleaner,the parts being shown in the position they occopy when the cleaner is tobe held in verti cal position when being pushed from the op erator. Fig.t is a similar view, the parts be ing represented in the position theyassume when the cleaner is to be held in vertical position and drawntoward the operator. Fi 5 is aview of the front of the cleaner, and Fi 6is a cross-sectional elevation of the cleaner.

Referring now to the general construction illustrated in the drawings, Ais a boiler of the horizontal type, provided with a packingbox, B,located at the front or rear of the boiler, as required, and near itslower side. A long steel or iron rod, a, is fitted tightly within thepacking-box B, and projects inward toward the opposite end of theboiler, and on the end of this rod there is loosely mounted a block, b,to which block there is hinged a brush-head, c, to which the wiresplints (I are attached. Upon either end of the head 0 there is ajournal carrying a small wheel, n, arranged to run upon the bottom ofthe boiler and support the brush-head in a horizontal position at aboutright angles to the rod a. Upon either side of the block I), and rigidlysecured to the rod a, are lugs or arms 0 0, arranged at right angles theone to the other, so that when the lug c is turned down to a verticalposition the lug 6 will be in a horizontal plane, the lug 0 being forthe purpose of driving the brush along the bottom of the boiler towardthe blow-off y, while the lug e is for the purpose of pulling the brushtoward the front of the boiler.

If the brush is to be pulled toward the front of the boiler withoutcarrying the aceumulated dirt or mud with it, the lug e is turned up,and then, when the rod a is drawn outward, the brush will be free toswing backward and be dragged along the bottom of the boiler.

Although we have described the blow-off as located at the rear end ofthe boiler, it will of course be understood that in certaincircumstances such blow-oil might be located at any point in the bottomof the boiler, or at its forward end. If, for instance, the blow-01fwere in the middle of the bottom of the boiler, the brush would be usedto push the mud from the forward end back toward the center, in whichcase the lug 0 would be turned down, but would be elevated the momentthe brush passed the blow-off, and so hold while the brush was beingpushed farther toward the rear, and when the brush was started on itsforward movement the lug 0 would be turned down and the brush held inrigid vertical position when being drawn forward toward the center.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent 1. A boiler-cleaner consisting, essentially, ofa rod, a, carrying fixed lugs c e, a block, b, and ahead-block, c,carrying splints or wires, substantially as described, and for thepurpose specified.

2. The combination, with a boiler, of a cleaner consisting, essentially,ofa brush hinged to a block loosely mounted on a rod between block ofthe brush being provided with small two fixed lugs, substantially as andfor the pur- Wheels, as at, substantially as described, and 10 posespecified.
